1.2 Turning the Power
On/Off
Power to the sensor may be turned on or off
at the mains switchboard.
Turn the mains switch on.
The sensor checks the program version,
LED, ROM, RAM and deviation status in that
order for proper operation.
Program version
The program version, denoted by the LEDs
in binary notation, is shown. For example,
the LED state shown on the next page
means the program version is “1.03”.
ROM, RAM check
AUTO LED lights: ROM is normal.
TRUE LED lights: RAM is normal.
(CALB and STATUS LEDs are always lit.)
Deviation status
All LEDs blink twice when the calibration is
completed.
After the diagnostic tests are completed;
•C-500 outputs heading data and the
STATUS LED lights immediately.
•PG-500 calculates the rate sensor offset.
The STATUS LED blinks during the
calculation, which takes about two minutes.
When the STATUS LED lights, bearing is
reliable.
Note: Confirm that the STATUS LED is lit
(not blinking) before leaving port.

1.3 Automatic Distortion
Compensation
Magnetic field distortion on your vessel has
been compensated at the installation. When
the magnetic field distortion changes, it can
be compensated automatically as follows.
Note: This function is only effective after
compensating for magnetic field
distortion. (Refer to page 10.)
1. Press the [AUTO] key more than two
seconds to light the AUTO LED.

2. To cancel automatic compensation, press
the [AUTO] key more than two seconds,
to turn off the AUTO LED.
Note 1: Do not conduct this procedure when
your boat is near a steel ship or iron
bridge, since they affect sensor
performance.
Note 2: Correct distortion whenever you feel
heading error is excessive.
1.4 Damping Control
The damping control determines how
sensitively the sensor responds to change of
ship’s heading. When the damping value is
large, the sensor responds smoothly but a
small boat may wander after the turning. Use
a small damping value as possible.
Note: When connecting with the autopilot
NAVpilot-500, use the default damping
setting (PG-500: damping 1, C-500:
damping 2).
1. Press the [DAMP] key more than two
seconds.
All LEDs go off, and then the current damping
setting is shown by the LEDs.

1.5 Selecting Output Data
Format
The sensor can output true or magnetic
heading. The default setting is magnetic, in
AD-10 format.
CAUTION
Turn off the autopilot before selecting
output data format.
The autopilot may turn the rudder suddenly.
To output true heading, do the following:
1. Connect Furuno GPS Navigator which
can output data sentence RMC or VTG.
2. Set up magnetic variation (manual or
automatic) at the GPS Navigator.
When RMC or VTG is input to the sensor, the
TRUE LED lights and then true heading is
output to other equipment.
4. To return to magnetic heading output,
disconnect the GPS Navigator.
Note 1: If the TRUE LED does not light
within 90 seconds, check the
navigator setting and cable
connection.
Note 2: If the sensor stops receiving
magnetic variation data while
outputting true heading, the TRUE
LED stops lighting and blinks. The
last-used variation data is used.
Note 3: Magnetic variation cannot be
corrected manually at the sensor.
Therefore, if you desire true heading
output but do not have a navigation
aid, you may enter appropriate
variation as shown in 3.4 Heading
Alignment on page 11. HDM
sentence, however, cannot be
changed to true heading. For HDG
sentence, it can be changed to true
heading at the equipment connected,
by using the magnetic heading and
magnetic variation data in the
sentence.
